摘要：
An apparatus for monitoring a vascular access comprises a dialysis circuit having a venous needle (18) and a blood pump (14) of a peristaltic type which generates oscillatory perturbations in the circuit. An optical sensor (19), arranged on a patients body by the venous needle, perceives the perturbations transmitted through the needle and sends a pulsating signal to an analysis device (20), absence of which pulsating signal provides an indication of a detachment of the needle.
